Thanks to everyone for all the suggestions, concerns and ideas. This is a project in conception phase, at this point I don't currently own a RV. I am leaning toward an Airstream camper but may go with a full blown RV. Printer or no printer won't effect that decision. I understand it will be much easier with an RV and perhaps very difficult / impossible with trailer. I have done extensive 'photo' trips in the past and always wished that I could produce some high quality large prints, especially as gifts to those I meet along the way. Long term camping throughout the country makes my desire to print even stronger. I will likely build a custom desk for my work / printing area, so I thought that I could build in some physical restraint as well as shock absorbing system to protect the printer, yet have it quick to 'open' to a usable printer. I have an Epson 3800 which I am just now replacing with a P800. I was planning on using the new printer but could use something else. My printing is exclusively B&W from my Leica M monochrom and typically on the larger sizes supported by this printer. These two printers produce superb B&W so are my preference.
